Thanks Darren. I saw another past post similar to this from you that seems to confirm this behavior as well. I was trying to be able to make the change to the Users email (as the Administrator) directly from the app since I am always on the Go and not in front of the computer to make the change in the Glide backend. Every other field updates perfectly but that Email field (no luck).
I guess I will have to open up the actual Google Sheet on my mobile and make the change directly to the data that way while on the Go. Thanks again!
